– CM and DDWoodyPC
In CrownMass Version 1.1.108, changes have been made to enhance the
error checking of data entries on the Analysis Area and Plots screen. Also, changes have been made to support
data entry of the 20-foot wind speed and dry bulb temperature on the Environment
Tab.
In DDWoodyPC Version 1.2.41, changes have
been made to enhance the error checking of data entries.

In CrownMass Version 1.1.107, enhancements have been made to allow for
both pulldown and manual entry of all values on the Analysis Area and Plots
Tab. In addition, changes have
been made to the handling of the situation where the surface fire rate of
spread is greater than the maximum crown rate of spread. CrownMass now displays a warning to
this effect and suggests the environmental conditions are unrealistic.
In Dispatcher’ Clock, Version 2.1.10, the
sunrise/sunset tables have been updated to be produced through 2010.

- CM
In CrownMass Version 1.1.101, changes have been made to the default
values and performance of the Surface Deposition columns on the Analysis Area
and Plots Tab. Recent user
feedback indicates that, at times, changes were being made to these values to
model fuel treatments. Depending
on the changes, incorrect estimates of canopy and surface fuels could occur.
The changes made in Version 1.1.101 will eliminate the potential for accidental
errors and also strengthen the ability of the program to model fuel treatments.

In CrownMass
Version 1.1.94, changes have been made to the calculation of crown weights for
Eastside and Westside Douglas-fir and Western Hemlock. The crown weight
equations in CrownMass were coded in 2000 to parallel those in the Federal
agency debris prediction programs. For Pacific Northwest (Westside) Douglas-fir
and Western Hemlock, the equations in the Federal agency debris prediction
programs were from Estimating the Weight of Crown Segments for Old Growth
Douglas-fir and Western Hemlock (Snell and Max, RP-PNW-329, January 1985).
Prior to this publication, the equations for the Pacific Northwest (Westside)
Douglas-fir and Western Hemlock were from Predicting Crown weight of Coast
Douglas-fir and Western Hemlock (Snell and Anholt, RP-PNW-281, March 1981). The
equations in RP-PNW-329 significantly over-predict crown weights for trees less
than 10 inches DBH. In addition, the equations in RP-PNW-329 were used to
calculate crown weights for Intermountain (Eastside) Douglas-fir and Western
Hemlock for DBH values greater than 34 and 32 inches respectively. This
resulted is significant changes in crown weights at this crossover DBH values.
In CrownMass Version 1.1.94, the following changes have been made:
The equations for Pacific Northwest (Westside) Douglas-fir crown weights have
been changed to use RP-PNW-281 (1981) for DBH values from 0-18 inches. For DBH
values greater than 18 inches, the equations in RP-PNW329 (1985) are used.
The equations for Intermountain (Eastside) Douglas-fir, the equations in
RP-PNW-329 were used to calculate crown weights for trees greater than 34
inches DBH. This created a significant weight decrease at the transition
DBH value. With this version of CrownMass, the equations for Intermountain
Douglas-fir crown weights have been changed to use RP-PNW-281(1981) for DBH
values greater than 34 inch DBH.
The equations for Pacific Northwest (Westside) Western Hemlock crown weights
have been changed to use RP-PNW-281 (1981) for all DBH.
The equations for Intermountain (Eastside) Western Hemlock, the equations in
RP-PNW-329 were used to calculate crown weights for trees greater than 32
inches DBH. This created a significant weight increase at the transition
DBH value. With this version of CrownMass, the equations for Intermountain
Western hemlock crown weights have been changed to use RP-PNW-281(1981) for DBH
values greater than 32 inch DBH.

DDWPC
Fixed error on
DDWPC Photo Series side. If there was information in the Note section,
the fuel loading report could not be created. This has been corrected in
version 1.2.39.
3/16/2003
-- CM
Changes made correct a problem with the calculation
of total fuelbed depth. This has
been corrected in version 1.1.92
3/16/2003 -- DDWPC
Changes made correct a problem with Photo
Series Inventories. Occurs when
selecting the first photo on the list, the data is not properly transferred
back to input grid. This has been
corrected in version 1.2.38.
2/24/2003 -- DDWPC
Changes made correct a problem when no 3+
materials were entered. In this
case the program could terminate.
This applies only to version 1.2.34 or later. Download DDWPC
1.2.37.
2/20/2003 -- DDWPC
Changes made to correct an error in the
calculation of percent error for Photo Series inventories. Download DDWPC 1.2.36.
1/28/2003 -- PSE
Changes made to correct a problem printing
fuel profile photos and comparison photos. Additionally, a printing problem associated with Windows XP
and ME was fixed. Download PSE 1.0.28 for the corrected application
1/14/2003 -- CM
Changes made to correct a problem that
caused a Crown Rate of Spread to be displayed when fire type was Surface
instead of zero. Download CM
1.1.89.
1/14/2003 -- DDWPC
Changes made to correct a problem with the calculation of foliage/needles. Download DDWPC 1.2.34 for the corrected application
6/28/2002 -- CM
Changes made to develop version 1.1.84
failed to deal with a potential divide by zero situation when the Fire Behavior
Tab was click on. Version 1.1.86 fixes this problem.
6/2/2002 -- CM
The calculation of Crown Fraction Burned (CFB) on the Fire Behavior Tab has been using an equation from Van Wagner (1977, 1993). The Farsite program (Finney 1998) implements CFB in a slightly different manner and this change in CrownMass, Version 1.84, implement fully the Farsite process. CFB calculations prior to Version 1.84 will be higher than those calculated with Version 1.84. The change only effects the crown fire rate of spread if an Active Crown Fire predicted by CrownMass.
5/12/2002 -- CM:
On the Analysis Area and Plots screen, the text box for Area Name allows for text up to 50 characters in length, including spaces. The text box allowed the user to enter more than 50 characters. When any process, such as calculations, was implemented which required writing information to the database, an error occurred. The program will no longer allow the user to enter more than 50 characters in the Area Name field.
4/3/2002 -- CM:
When entering loading in the Surface Fuel Model tab for current surface loading you were only able to enter whole number. This has been fixed to allow the entry of numbers containing fractional values. Please download CM version 1.1.80.
4/3/2002 -- CM:
A number of changes have been incorporated
into this version of Crown Mass (CM) version 1.1.78.
Plot Canopy
Base and Ceiling Heights
The method for
handling Canopy Base(CBH) and Ceiling Heights(CCH) in plots where the one foot
bulk density does not exceed the Critical Bulk Density identified on the
Assumptions Tab has been changed.
Instead of using an average of the stand heights as a surrogate, the CBH
and CCH are now not calculated and indicated as such by an N/C (not calculable)
in the appropriate boxes.
This also affects the Analysis Area’s CBH and CCH values. If no plots have a one foot bulk
density that exceeds the Critical Bulk Density, then the CBH and CCH values for
the Analysis Area are marked N/C.
Only those plots in an Analysis Area that have a one foot bulk density
that exceeds the Critical Bulk Density are used to compute the Analysis Area’s
CBH and CCH. This has a
corresponding effect of the statistics for CBH. Warnings have been added to alert users any plots that did
not meet the CBD.
In addition,
Stand Height for each Plot and Analysis Area has been added. Several minor fixes have also been
included in this release including the Tab progression order on the Environment
Tab.
3/12/2002 -- DDWPC:
The total area tons per acre on the summary
graph and on the loading report did
not include needles. This has been fixed in 1.2.32
1/23/2002 -- CM:
CM was not accepting the number of trees per
acre to the level of
resolution should in the FVS tree list. It was rounding up resulting in an
overestimation of tree per acre. All past FVS imports should be re-evaluated.
Start with a New CrownMass Inventory and import the FVS tree list.
Perform a new analysis using this CM 1.69 and the new FVS import.
1/9/2002 -- CM:
